DESCRIPTION:One of the main questions in the context of the universality a
nd conformal invariance of a critical 2D lattice model is to find an embed
ding which geometrically encodes the weights of the model and that admits
“nice” discretizations of Laplace and Cauchy-Riemann operators.\n\n
We establish a correspondence between dimer models on a bipartite graph
and circle patterns with the combinatorics of that graph. We describe how
to construct a circle pattern embedding of a dimer planar graph using its
Kasteleyn weights. This embedding is the generalization of the isoradial
embedding and it is closely related to the T-graph embedding.\n\n Bas
